Safety Instructions
All instructions must be read and observed. The safeguards integrated into the
measuring tool may be compromised if the measuring tool is not used in
accordance with these instructions. STORE THESE INSTRUCTIONS IN A SAFE PLACE.
▶ Have the measuring tool serviced only by a qualified specialist using only
original replacement parts. This will ensure that the safety of the measuring
tool is maintained.
▶ Do not use the measuring tool in explosive atmospheres which contain
flammable liquids, gases or dust. Sparks may be produced inside the measuring
tool, which can ignite dust or fumes.
▶ The measuring tool may not be 100 % accurate for technological reasons. To
eliminate hazards, familiarise yourself with further sources of information,
such as building plans and photographs taken during construction, etc. before
carrying out any drilling, sawing or routing work on walls, ceilings or
floors. The accuracy of the measuring tool may be affected by environmental
influences, such the level of humidity or there being other electronic devices
nearby. The structure and condition of the walls (e.g. damp, building
materials containing metal, electrically conductive wallpaper, insulating
materials, tiles) and the number, type, size and position of the objects may
distort the measuring results.
▶ Make sure that you are properly earthed when taking measurements. If you are
not properly earthed (e.g. by wearing insulating footwear or by standing on a
ladder), it will not be possible to locate live cables.
▶ If there are gas pipes in the building, check to ensure that none of them
have been damaged after completing any work on walls, ceilings or floors.
▶ Live wires can be detected more easily when power consumers (e.g. lamps,
appliances) are connected to the wire being sought and switched on. Switch off
power consumers and make sure that live cables are de-energised before
drilling, sawing or milling into walls, ceilings or floors. After performing
any kind of work, check to ensure that objects placed on the base material are
not live.
▶ When attaching objects to dry walls, and in particular when attaching them
to the substructure, check to ensure that both the wall and the fastening
materials have a sufficient load-bearing capacity.

Technical data
Assembly
Inserting/changing the batteries
It is recommended that you use alkaline manganese batteries to operate the
measuring tool. To open the battery compartment cover (8), press the locking
mechanism (9) and lift open the battery compartment cover. Insert the
batteries. When inserting the batteries, ensure that the polarity is correct
according to the illustration on the inside of the battery compartment. Always
replace all the batteries at the same time. Only use batteries from the same
manufacturer and which have the same capacity. u Take the batteries out of the
measuring tool when you are not using it for a prolonged period of time. The
batteries can corrode and self-discharge during prolonged storage in the
measuring tool.
Operation
▶ Protect the measuring tool from moisture and direct sunlight.
▶ Do not expose the measuring tool to any extreme temperatures or variations
in temperature. In case of large variations in temperature, leave the
measuring tool to adjust to the ambient temperature before switching it on.
The precision of the measuring tool may be compromised if exposed to extreme
temperatures or fluctuations in temperature.
▶ Avoid hard knocks to the measuring tool or dropping it. After severe
external influences and in the event of abnormalities in the functionality,
you should have the measuring tool checked by an authorised Bosch after-sales
service agent.
▶ Certain ambient conditions fundamentally impair the measuring results. These
include, e.g. the proximity of devices that generate strong electric, magnetic
or electromagnetic fields, moisture, metal building materials, foil-laminated
insulation materials or conductive wallpaper or tiles. Therefore, also refer
to other information sources (e.g. construction plans) before drilling, sawing
or routing into walls, ceilings or floors.
▶ Hold the measuring tool by the intended gripping surface (1) only, so as not
to influence the measurement.
▶ Do not attach any stickers or labels to the sensor area (6) on the rear of
the measuring tool. Metal labels in particular will affect measuring results.
Starting Operation
Switching on/off
▶ Before switching on the measuring tool, ensure that the sensor area (6) is
dry. If necessary, use a cloth to dry the measuring tool.
▶ If the measuring tool has been exposed to a significant change in
temperature, leave it to adjust to the ambient temperature before switching it
on.
To switch on the measuring tool, push the on/off switch (2) down.
The measuring tool carries out a short self-check and calibrates itself
automatically. Once the indicator light (3) turns green, the measuring tool is
ready to use.
To switch off the measuring tool, push the on/off switch (2) up.
If no measurement takes place for approx. 10 minutes, the measuring tool
automatically switches off to save the batteries.
Note: When the measuring tool has switched off automatically, the on/off
switch (2) will still be in the “on” position. To switch the measuring tool on
again, first switch it off and then switch it on again.
How it Works
The measuring tool checks the substrate of the sensor area (6) up to the maximum detection depth. Metal objects and live cables are automatically searched for during each measurement.
Objects are only displayed roughly the first time you move over them. Move the
measuring tool several times over the same surface in order to locate the
object precisely.
The detection depth of the measurement depends on material and size of the
objects, as well as material and condition of the substrate and may be less
than the maximum detection depth.
▶ Before drilling, sawing or routing into walls, refer to other sources of information to ensure that you eliminate hazards. Since the measuring results can be influenced by ambient conditions or the nature of the wall, there may be a hazard even though no audio signal is emitted and the indicator light (3) lights up green.
Searching for Metal Objects
When approaching a metal object, the indicator light (3) first lights up
yellow, then changes to red and an audio signal is emitted. The pitch of the
audio signal increases as the metal object is approached. If the metal object
is below the centre of the sensor range (6), the pitch will be at its highest.
▶ Even when the indicator light is yellow, there may be a metal object below
the sensor range. Small or deep-lying metal objects are near the sensor, or
the nature of the wall affects the measuring result.
Searching for Live Cables The measuring tool displays single-phase live cables
(110-240 V, 50-60 Hz). Other cables (multi-phase electricity cables, DC,
higher/lower frequency or voltage) as well as non-live cables cannot be
reliably detected, but they may be displayed as metal objects.
Preparing to take measurements and features of the measuring process: The
cable must be live. You should therefore connect electricity consumers (e.g.
lights, appliances) to the electricity cable you are trying to find. Switch on
the electricity consumers to ensure that the electricity cable is live.
The 5060 Hz signal from the electricity cable must be able to reach the
measuring tool. If the cable is in damp walls (e.g. due to high humidity),
behind metallic foils (e.g. from thermal insulation) or in an empty metal
pipe, the signal will not reach the measuring tool and you will not be able to
find the cable. If the indicator light (3) lights up yellow or red over a
larger range, then the material is electrically shielded and the search for
live cables is not reliable.
The measuring tool must be sufficiently earthed. To do this, hold it firmly
(without gloves) by the gripping surface (1). Make sure that you are in good
contact with the floor. Insulating shoes, ladders or platforms may compromise
your contact with the floor. The floor must also be earthed in order for live
cables to be detected.
The 5060 Hz signal from the electricity cable must be stronger along the
cable than in its immediate vicinity. If the wall is very dry or poorly
earthed, the signal will be the same strength throughout the wall. This will
result in the measuring tool indicating that it has found a signal over a
large area, but it will not be able to detect the exact location of the cable.
In this instance, it may be helpful to place your free hand on the wall 20-30
cm from the measuring tool in order to conduct the signal away from the wall.
If a live cable is found, the indicator light (3) flashes red and a pulsating
audio signal will sound at a fast rate.
Working Advice
Marking objects If required, detected objects can be marked. Perform a
measurement as usual. Once you have found the boundaries or the centre of an
object, mark the sought location at the top marking aid (5) and the side
marking aid (4). Connect the points with a vertical and horizontal line. The
boundary or the centre of the object is located where the lines intersect.
Recalibration Manually recalibrate the measuring tool if the indicator light
(3) continues to light up yellow or red even though there is no metal near the
measuring tool.
– Switch on the measuring tool using the on/off switch (2).
– Remove a battery from the measuring tool whilst it is switched on.
– Switch off the measuring tool using the on/off switch (2) after the battery
has been removed.
– Reinsert the battery into the measuring tool. Ensure that the polarity is
correct.
– Remove all objects near the measuring tool (including watches or metal
rings) and hold the measuring tool in the air.
– Switch the measuring tool on and off again within 3 s using the on/off
switch (2). The indicator light (3) will flash red slowly for the 3 s to
indicate readiness for calibration.
– Switch the measuring tool back on within 0.5 s. The calibration will start
and take roughly 6 s. During calibration, the indicator light (3) flashes
green at a fast rate. Once the indicator light lights up green continuously,
the calibration is complete and the measuring tool is ready to use.
Note: If the sequence of switching off and switching on again is not observed, calibration will not take place. The indicator light (3) continues to light up yellow or red even though there is no metal nearby. In this case, repeat the calibration in the exact same way.
